Abstract

The antiflooding valve has a flap (K) pivoted around an overhead axis (X) relative to a seat with flat seat opening. A hinge (G) is provided in the flap between the axis and an underlying flap area spaced from the axis below the center of the flap. The hinge is arranged below a flow axis of the seat by pressing the flap at the seat opening. An independent claim is included for a flap which is a plastic molded part.
